Caffeine: it's what's for dinner.

OK, just kidding (sort of)...but if you are looking for general re-assurance about the beneficial effects of consuming caffeine, then you will want to give a read to a May 2009 article, "Winning With Caffeine," in Men's Journal. The story's secondary headline reads, "It's the last legal performance enhancer, and studies show it really does give jocks an edge."

Just remember: (most everything) in moderation, though when it comes to XS Energy Drinks, your definition of "moderate" may vary from the next citizen of XS Nation.
